OBOGS for the A400M [ Return towards  Military cargo aircrafts  ]

Air Liquide, fresh from the experience gained in developing the Rafale and the A380, is participating in the programme to build the A400M, the new military transport aircraft developed and manufactured by a company that hitherto has operated solely in the civilian aviation field.
Compared with conventional solutions for storing small quantities of oxygen, the direct on-board generation capacity of the Air Liquide OBOGS gives the aircraft greater availability and flexibility.
The oxygen generator is specific to the A400M, intermediate in size between the ones fitted to fighter aircraft and those designed for the A380. It is designed to satisfy the oxygen needs of between five and seven crew members and can provide oxygen enriched air at varying rates depending on the altitude.

This new OBOGS model includes new generation programmable electronics developed under the requirements of standard DO 254, a highly elaborate system of self-diagnosis that cuts back on repair times and an outlet flow regulation valve, and a valve for monitoring equipment performance on an ongoing basis and automatically selecting the oxygen supply mode between cylinders or OBOGS.
